Repair Broken Double Pane Window Glass

Repairing a Broken Double Pane Window Glass

Rich Sinclair who lives in Hainesport, New Jersey emailed me asking the following question:

"Can you replace only one broken pane of a double pane window?"

The answer is simply: No

Double pane, or insulated glass, is made by taking two pieces of glass and separating them with a special spacer that has an adhesive on it. The space between the two panes of glass is filled with argon gas at the factory.

It's virtually impossible to peel off the broken glass from the seal spacer and then install a new piece of glass.

One Response to Repair Broken Double Pane Window Glass

Do you find that most insulated glass windows like this -- the homeowner can replace broken glass themselves? Assuming they are replacing both of the double panes?

I deal mostly with old windows in my practice where replacing a part here and there is relatively easy. I'm curious whether your experience is that new windows are often easy to repair by the homeowner or whether a pro should be called.
